Display system

ABSTRACT

Control System for a data display system such as a scoreboard, message board or the like wherein display indicators having location addresses, on the board, are addressed and actuated through a logic system which first receives and stores address data pertaining to a particular indicator, receives display character data, and automatically reads out the address data to the board for enabling the desired indicator followed by the display character data to actuate it to display the desired character. A buffer memory is provided for controlling the input to the logic system from a variety of input devices including console keyboard, punch tape typewriter and reader as well as magnetic memory storage devices. Circuits are provided in conjunction with the buffer for updating particular message data existing in the buffer as required by changes in the game or other information.
